Studies of ancient pathogens are moving beyond simple confirmatory analysis of diseased bone; bioarchaeologists and ancient geneticists are posing nuanced questions and utilizing novel methods capable of confronting the debates surrounding pathogen origins and evolution, and the relationships between humans and disease in the past. This dissertation examines two ancient human diseases through molecular and bioarchaeological lines of evidence, relying on techniques in paleogenetics and phylogenetics to detect, isolate, sequence and analyze ancient and modern pathogen DNA within an evolutionary framework. Specifically this research addresses outstanding issues regarding a) the evolution, origin and phylogenetic placement of the pathogen causing skeletal tuberculosis in New World prior to European contact, and b) the phylogeny and origins of the parasite causing the human leishmaniasis disease complex. An additional chapter presents a review of the major technological and theoretical advances in ancient pathogen genomics to frame the contributions of this work within a rapidly developing field. This overview emphasizes that understanding the evolution of human disease is critical to contextualizing relationships between humans and pathogens, and the epidemiological shifts observed both in the past and in the present era of (re)emerging infectious diseases. These questions continue to be at the forefront of not only pathogen research, but also

bioarchaeological and paleopathological scholarship.

This research focuses upon the intersection of social complexity and leadership among commoners in complex societies as expressed through mortuary ritual. I study how ideology, materialized through treatment of the deceased body, was a potential source of power among commoners in ancient Maya society and how this materialization changed through time. Mortuary data are drawn from mid-level settlements of the Belize River Valley, located in western Belize within the eastern Maya lowlands. The primary research question addresses whether mid-level leaders in the Belize River Valley targeted certain human bodies for ancestral veneration through tomb re-entry and ritual interaction with skeletal remains. The ritual-political strategy of mid-level leaders is measured using archaeothanatology, an analysis of grave taphonomy based on forensic data, to reconstruct cultural beliefs about death based on treatment of deceased bodies, radiogenic strontium isotope analysis to reconstruct residential history, and analysis of dental metrics to assess biological kinship. While preservation of osseous material was poor, results indicate that the frequency of disarticulated and secondary burials was higher in eastern structures than in other locales, although eastern structures were not the only loci of these types of deposits. Overall, it does not seem like secondary burials were regularly and purposefully created for use as ritual objects or display. Radiogenic strontium isotope data enrich this analysis by showing that eastern structures were not a burial locale exclusive to individuals who spent their childhood in the Belize Valley. Data from upper-level eastern structures also suggests that within that part of society local birth did not guarantee interment in a local manner; perhaps the social network created during one's life shaped treatment in death more than residential origin. Biological distance analyses were inconclusive due to missing data. Comparison of mortuary practices to nearby regions shows distinct mortuary patterning across space and time. This is consistent with reconstructions of ancient Maya sociopolitical organization as regionally diverse and moderately integrated.

Bioarchaeologists often use dental data and spatial analysis of cemeteries to infer the biological and social structure of ancient communities. This approach is commonly referred to as biological distance (“biodistance”) analysis. While permanent crown data feature prominently in these efforts, few studies have verified the accuracy of biodistance methods for recognizing child relatives using deciduous teeth. Thus, as subadults comprise an essential demographic subset of mortuary assemblages, deciduous phenotypes may represent a critical but underutilized source of information on the underlying genetic structure of past populations. The goal of the dissertation is to​ quantitatively analyze the developmental program underlying deciduous phenotypes and​ to evaluate their performance in accurately reconstructing known genealogical relationships.​ This project quantifies morphological variation of deciduous and permanent tooth crowns from stone dental casts representing individuals of known pedigree deriving from three distinct populations: European Canadians, European Australians, and Aboriginal Australians.

To address the paucity of deciduous-focused validation research, phenotypic distances generated from the dental data are subjected to performance analyses (biodistance simulations) and compared to genetic distances between individuals. While family-specific results vary, crown morphology performs moderately well in distinguishing relatives from non-relatives. Comparisons between deciduous and permanent results (i.e., Euclidean distances, Mantel tests, multidimensional scaling output) indicate that deciduous crown variation provides a more direct reflection of the underlying genetic structure of pedigreed samples. The morphology data are then analyzed within a quantitative genetic framework using maximum likelihood variance components analysis. Novel narrow-sense heritability and pleiotropy estimates are generated for the complete suite of deciduous and permanent crown characters, which facilitates comparisons between samples, traits, dentitions, arcades, antimeres, metameres, scoring standards, and dichotomization breakpoints. Results indicate wide-ranging but moderate heritability estimates for morphological traits, as well as low to moderate integration for characters within (deciduous-deciduous; permanent-permanent) and between (deciduous-permanent) dentitions. On average, deciduous and permanent homologues are more strongly genetically correlated than characters within the same tooth row. Results are interpreted with respect to dental development and biodistance methodology. Ultimately, the dissertation empirically validates the use of dental morphology as a proxy for underlying genetic information, including deciduous characters.

Social identities are fundamental to the way individuals and groups define themselves. Archaeological approaches to social identities in the Andes emphasize the importance of group identities such as ethnicity and community identity, but studies of gender and age identities are still uncommon. In this dissertation, I build on these earlier approaches to Andean social identities and consider community, gender, and age identities at the site of Chiribaya Alta using case studies.

The coastal Ilo Chiribaya polity is associated with the Andean Late Intermediate Period in the lower Osmore drainage of southern Peru. Previous analyses indicate that Chiribaya sites in this area formed a señorío, an Andean chiefdom with separate occupational groups of fishers and farmers. The most complex excavated Chiribaya site in this region is Chiribaya Alta. At this time, excavations have sampled nine of the cemeteries present at the site. Two of these cemeteries, four and seven, have the most elaborate burials at the site and are each associated with different occupational communities.

This dissertation examines community, gender, and age identities at Chiribaya Alta through the use of three case studies. The first case study argues that the iconographic designs on coca bags interred with the dead signified occupational community identities. Coca bags buried in cemetery four have designs relating to mountains and farming, whereas those from cemetery seven have symbols associated with water. These designs correspond to the occupational community groups associated with each of these cemeteries. The second case study uses grave good presence and absence to examine the nature of gender roles and identity at Chiribaya Alta. Multiple correspondence analysis indicates that normative gender roles are reflected in grave good assemblages, but that gender identity was flexible at the individual level. The final case study presents newly generated age-at-death estimations using transition analysis combined with mortuary analyses to explore the manner in which gender and age intersect for older individuals at Chiribaya Alta. This final paper argues that there is an elderly identity present amongst individuals at Chiribaya Alta and that gender and age intersect to impact the lives of older men and women differently.

Migrations, past and present, fundamentally influence human interaction, community building, and social evolution. Studies of contemporary migrations demonstrate that the form and intensity of interaction migrants maintain between homeland and host communities shape social dynamics, innovations, and identities. This dissertation applies a contemporary theoretical framework and biogeochemical analyses to elucidate the scale, processes, and impacts of migration in the hinterland of the pre-Hispanic Tiwanaku polity (ca. AD 500-1100). Social diversity is examined by reconstructing the migration histories and dietary choices of individuals interred at the Tiwanaku-affiliated site of Omo M10 in the Moquegua Valley of southern Peru.

Radiogenic strontium and stable oxygen isotope data from human dental and skeletal elements are used to characterize intra- and inter-individual paleomobility patterns at Omo M10. When contextualized with archaeological evidence, these data reveal multigenerational interaction through migration between communities in the highland Tiwanaku heartland and at Omo M10. The observed greater mobility of females and juveniles at Omo M10 indicates that women and families played an essential role in maintaining social relationships and persistent cultural continuity in Moquegua Tiwanaku life. Contact with the highlands waned over time as disruption in the urban highland centers likely weakened ties to peripheral lowland communities.

Stable carbon and nitrogen data from human dental and skeletal elements are employed to estimate intra- and inter-individual paleodietary patterns. Results indicate diet at Omo M10 varied depending on an individual’s community affiliation, sex, age, and level of mobility; diet broadly changed over time with shifting levels of interaction with highland Tiwanaku communities. Intra-individual biogeochemical analyses of migration and diet at Omo M10 contribute a nuanced perspective on the diverse experiences of multigenerational colonists on the periphery of the Tiwanaku polity.

In anthropological models of social organization, kinship is perceived to be fundamental to social structure. This project aimed to understand how individuals buried in neighborhoods or patio groups were affiliated, by considering multiple possibilities of fictive and biological kinship, short or long-term co-residence, and long-distance kin affiliation. The social organization of the ancient Maya urban center of Copan, Honduras during the Late Classic (AD 600-822) period was evaluated through analysis of the human skeletal remains drawn from the largest collection yet recovered in Mesoamerica (n=1200). The research question was: What are the roles that kinship (biological or fictive) and co-residence play in the internal social organization of a lineage-based and/or house society? Biodistance and radiogenic strontium isotope analysis were combined to identify the degree to which individuals buried within 22 patio groups and eight neighborhoods, were (1) related to one another and (2) of local or non-local origin. Copan was an ideal place to evaluate the nuances of migration and kinship as the site is situated at the frontier of the Maya region and the edge of culturally diverse Honduras.

The results highlight the complexity of Copan’s social structure within the lineage and house models proposed for ancient Maya social organization. The radiogenic strontium data are diverse; the percentage of potential non-local individuals varied by neighborhood, some with only 10% in-migration while others approached 40%. The biodistance results are statistically significant with differences between neighborhoods, patios, and even patios within one neighborhood. The high level of in-migration and biological heterogeneity are unique to Copan. Overall, these results highlight that the Copan community was created within a complex system that was influenced by multiple factors where neither a lineage nor house model is appropriate. It was a dynamic urban environment where genealogy, affiliation, and migration all affected the social structure.

This dissertation focuses on the diversity inherent to the process of social community construction. Building upon previous archaeological and bioarchaeological studies of community identities, the current project emphasizes the need for consideration of the impact of diversity on community identity formation in the past and illustrates the utility of a bioarchaeological approach for undertaking this task. Three specific aspects of community formation are addressed: (1) the relationship between symbolic community boundaries and geographic space, (2) the influence of diverse discourses of intra-community sub-groups on community formation, and (3) the negotiation of community boundaries by outsiders. To investigate these aspects of community construction in the past, dietary practices and mortuary rituals of the Late Intermediate Period (c. AD 900-1470) Ychsma society of the central Peruvian coast are examined as a case study. Previous anthropological and sociological studies demonstrate that diet and burial customs are common mechanisms used in processes of group identification around the world, including the Andes. In the current study, analyses of materials from Armatambo and Rinconada Alta in the Rimac Valley are used to examine the ways in which isotopic and dental indicators of diet and archaeological contextual indicators of mortuary rituals correspond with or crosscut spatial burial patterns and additional groups based on sex, age at death, and biogeochemically reconstructed residential origins. Observed patterns are interpreted using a theoretical framework that incorporates sociocultural theory of identity with pre-Columbian Andean ideology of the body, self, and social environment. Results reveal differences in large-scale trends in diet and mortuary practices associated with burial at each site that are interpreted as evidence of symbolic community boundaries between sites. Complexities within larger trends reveal evidence of internal diversity as well as fluidity across community boundaries. Specifically, evidence is presented for intra-community dietary differences, intra-community differences associated with age and sex, and finally evidence of external relationships. This consideration of diversity in community identity construction is concluded to profoundly refine current understandings of Ychsma social interactions. Consequently, this study demonstrates empirical investigation of social diversity is necessary for understanding the complex nature of the social construction of communities in the past.

Many models of colonial interaction are build from cases of European colonialism among Native American and African peoples, and, as a result, they are often ill-suited to account for state expansion and decline in non-Western contexts. This dissertation investigates social organization and intraregional interaction in a non-western colonial context to broaden understanding of colonial interaction in diverse sociocultural settings. Drawing on social identity theory, population genetics, and social network analysis, patterns of social organization at the margins of the expansive pre-Hispanic Tiwanaku state (ca. AD 500-1100) are examined.

According to the dual diaspora model of Tiwanaku colonial organization in the Moquegua Valley of southern Peru, Chen Chen-style and Omo-style ethnic communities who colonized the valley maintained distinct ethnic identities in part through endogamous marriage practices. Biodistance analysis of cranial shape data is used to evaluate regional gene flow among Tiwanaku-affiliated communities in Moquegua. Overall, results of biodistance analysis are consistent with the dual diaspora model. Omo- and Chen Chen-style communities are distinct in mean cranial shape, and it appears that ethnic identity structured gene flow between ethnic groups. However, there are notable exceptions to the overall pattern, and it appears that marriage practices were structured by multiple factors, including ethnic affiliation, geographic proximity, and smaller scales of social organization, such as corporate kin groups.

Social network analysis of cranial shape data is used to implement a multi- and mesoscalar approach to social organization to assess family-based organization at a regional level. Results indicate the study sample constituted a social network comprised of a dense main component and a number of isolated actors. Formal approaches for identifying potential family groups (i.e., subgroup analysis) proved more effective than informal approaches. While there is no clear partition of the network into distinct subgroups that could represent extended kin networks or biological lineages, there is a cluster of closely related individuals at the core of the network who integrate a web of less-closely related actors. Subgroup analysis yielded similar results as agglomerative hierarchical cluster analysis, which suggests there is potential for social network analysis to contribute to bioarchaeological studies of social organization and bioarchaeological research in general.

Violence has been characterized as a force for both political change and maintenance of the status quo in human societies. The present study examines how outbreaks of violent events led to a legacy of prolonged warfare among neighboring communities and shaped the formation of new political institutions during the late prehispanic era in the North-Central Andes. Drawing on data collected through archaeological excavation, osteological analysis of human remains, and radiocarbon dating, this work reconstructs life and death histories of 287 individuals recovered from nine archaeological sites to investigate diachronic patterns in physical violence. The observed individuals inhabited settlements located within the high-altitude, mountainous terrain of the Callejón de Huaylas, a region that has received little attention from bioarchaeologists, and the majority lived during the Late Intermediate Period (1000-1450 CE). Archaeological research has indicated local livelihoods changed significantly around 1000 CE. In the wake of Wari state disintegration and an increasingly arid climate, communities faced a series of social, political, and economic transformations. Less is known about how these shifts affected embodied practices of violence in the region. This study documents a stark change in who experienced head injuries during the Late Intermediate Period, as compared to data from preceding eras. Individuals of all ages exhibited both antemortem and perimortem trauma throughout the four and a half centuries. Results reveal people experienced novel forms of physical violence beginning in the mid-1200s—not only did more individuals sustain head injuries, including juveniles, but the inflicted trauma was more lethal and severe at this time. These trauma patterns persisted for generations, continuing through Inka conquest around 1450 CE. The frequency and type of observed cranial trauma are consistent with warfare documented ethnographically among some small-scale societies, suggesting an association between violence and political autonomy. Beyond identifying cultural transformations in victim identities and intergroup dynamics, this research contributes to a growing body of work across the Americas investigating mounting evidence of social strife and conflict from the 13th to 15th centuries. Finally, it sheds light on intergenerational consequences of violent actions by centering individual experiences within contexts of long-term historical trajectories.

This dissertation addresses the role of kinship and residential mobility during the transition from Final Neolithic to Early Bronze Age (ca. 3500 – 2500 BC) in Attica, Greece. It examines descent systems, ancestor formation, and the interplay between biological, social, and spatial structure in mortuary practices. It also evaluates the nature and degree of residential mobility and its potential role in the formation and maintenance of social networks. Archaeological hypotheses on the kin-based structure of formal cemeteries, the familial use of collective tombs, marriage practices and mate exchange, and relocation were tested focusing on the Early Helladic cemetery of Tsepi at Marathon. Tsepi constitutes the earliest formally organized cemetery on the Greek mainland and it has also contributed to enduring debates over the nature of the interaction between the eastern Attic coast and the central Aegean islands.

This study integrates osteological, biogeochemical, and archaeological data. Inherited dental and cranial features were used to examine biological relatedness and postmarital residence (biodistance analysis). Biochemical analysis of archaeological and modern samples was conducted to examine the geographic origins of the individuals buried in the cemetery and reconstruct mobility patterns. Osteological and biogeochemical data were interpreted in conjunction with archaeological and ethnographic/ethnohistoric data.

The results generally supported a relationship between spatial organization and biological relatedness based on phenotypic similarity at Tsepi. Postmarital residence analysis showed exogamous practices and tentatively supported higher male than female mobility. This practice, along with dietary inferences, could also be suggestive of maritime activities. Biogeochemical analysis showed a local character for the cemetery sample (96%). The common provenance of the three non-local individuals might reflect a link between Tsepi and a single locale. Burial location was not determined by provenance or solely by biological relatedness. Overall, the results point towards more nuanced reconstructions of mobility in prehistoric Aegean and suggest that burial location depended on a complex set of inter-individual relationships and collective identities. The contextualized bioarchaeological approach applied in this study added to the anthropological investigations of social practices such as kin relations (e.g., biological, marital, social kinship) and residential relocation as diachronic mechanisms of integration, adaptation, or differentiation.
